Intro

Every carbon number carbmee produces for a customer starts as someone else's mess: a dozen ERP exports, mismatched supplier spreadsheets, transactional data that doesn't line up with product data, emissions factors that don't map cleanly to anything. As a Sustainability Data Engineer, you build the pipelines that turn that mess into carbmee EIS™'s single source of truth: the foundation of every Corporate, Supply Chain, and Product carbon footprint (CCF, SCF, PCF) we calculate is built on.

This is an infrastructure-and-integration role first, sustainability domain role second, but the two aren't separable here. You'll be the person who decides how a customer's SAP data actually maps into our schema, what happens when a required field is missing, and how a pipeline scales from one pilot customer to twenty enterprise deployments without falling over.

Your tasks

• Design and build the ETL pipelines that ingest customer data: PLM/product data and transactional data - from ERP systems (especially SAP), procurement platforms, and flat files, and transform it into carbmee's data model.
• Own data quality logic: field validation, deduplication, handling missing values, and encoding the judgment calls (e.g., when missing weight data forces a fallback from activity-based to spend-based emissions estimation) that keep a pipeline from silently producing wrong numbers.
• Build and maintain the integrations connecting carbmee EIS™ to customer systems via APIs, custom scripts (Python, SQL), and batch/streaming data pipelines.
• Work with LLM-assisted mapping tools (we use Claude extensively) to accelerate transformation work, while building the guardrails that catch when a model would mismap a column it doesn't have context for.
• Partner with customer IT and data teams directly to understand system architecture and resolve integration blockers.
• Feed recurring data-quality patterns back to carbmee's product and engineering teams so the platform gets smarter with every deployment, not just more scripts.
• Contribute to the internal tooling and templates that let the next Sustainability Data Engineer or Forward Deployed Engineer onboard a new customer faster than you did.

Your profile

Who you are
Associate: you have relevant experience (internships, working student roles, or 1-2 years full-time) in data engineering, backend development, or a technical consulting environment, with strong fundamentals in Python and SQL and genuine curiosity about the sustainability domain.

Senior: you have a proven track record building and scaling production data pipelines (ideally including ERP integrations - SAP a strong plus) and are comfortable owning architecture decisions with minimal oversight. Prior exposure to carbon accounting, ESG data, or regulatory reporting (CBAM, CSRD) is a strong plus but not required if your data engineering fundamentals are excellent.

• Strong command of Python and SQL; experience with cloud platforms (AWS, GCP, or Azure) and ETL/data pipeline tooling.
• Comfort with genuinely messy, real-world enterprise data, and the skepticism to validate rather than assume it's clean.
• Ability to work directly with customer technical stakeholders, not just internal teams.
• Degree in Computer Science, Data Engineering, or a related field, or equivalent practical experience.
• Fluent in English and German.
• Based in Munich.
